' Noreau-,3.874

To aZZ'f-whom 'it mlvyfcohcemf l [Be it known that I, EDWARD E; E'ITER,

. citizen vof the United States, residing at Turtle Creek, in the countyof Allegheny and 4 State of Pennsylvania, have invented certam new anduseful Improvements in Nursing-Bottles, of which the following is a ospecification.

This invention comprehends certain 'new and useful improvements innursing bottles of that type that are designed to admit air into thebottle as the contents are withdrawn therefrom, and' one of the objectsof the invention is a sim le and efficient construction of nursingbottllell of this character, whiclris composed of comparatively fewparts that may be cheaply manufactured and readily assembled. And afurther object of the invention is a nursing bottle of this type', theair inlet means of which are embodied in a cap adapted to be secured tothe open-base body portion of the bottle, so that the cap,

may be easily detached Whenevernecessary for the purpose of cleansingthe bottle, which manifestly may thus be more easily effected than whenthe neck portion thereof must alone be depended upon forthis purpose.

With these and other objects in view that will more fully appear as thedescription proceeds, the invention consists in certain constructionsand arrangements of the parts that I shall hereinafter fully vdescribeand claim. A

Fora full understanding of the invention and the merits thereof, and toacquire a knowledge of the details of construction, reference is to behad tothe following description and accompanying drawing, in

which Figure 1 is a longitudinal sectional view of a bottle constructedvin accordance With my invention,"a portion thereof being shown in sideelevation; Fig. 2 is a detail top plan view of the bottle cap detached;Fig. 3 is a detail perspective view of the valve employed; and, Fig. 4is a sectional view of the base portion of the bottle, illustrating thevalve in the raised or open position which it will assume in theoperation of withdrawing the contents of the bottle throughthe nippleend thereof. l

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views o the drawing, by the same referencecharacters.

Specification ofLetters Application led June 26,

isos. seal No. acaso,

. -.Referring to the drawing, thenumeral 1 designates the body portionof a nursing bottle which may be of any desired construction anddesign', -2 the neck thereof and 3 the nipple which mayl also be of any.desired material, construction or design, as I'do not deadnuttmg airinto the bottle as the contents are sucked therefrom. In the presentinstance, the body ortion 1 of the bottle is constructed entire open atthe bottom and is designed to be cfosed b means of a cap of metal or anyother desire material, said cap being detachably secured to the baseortion of the body'l by means of the threaded engagement of the sides 5of the cap with exterior screw threads formed on the body portion nearthe lower end thereof. The cap 4 is formed with a preferably centrallydisposed raised portion 6, and around the margin of said raised portionwith a circular series of apertures 7.

The valve in the bottle, in the present instance, comprises a disk-likemembrane 8 of rubber or 'similar substance, and it is formed with apreferably centrally located slit 9 formed, for instance, byan incisionin the material of which the valve is constructed. The valve 8 is formedwith a thickened rim 10 which may be interposed between the lower edgeof the body portion and the cap 4, as clearly illustrated 1n Figs. 1 and4, so as to securely hold the valve in lace, and at the same timesubserve the a ditional function of a seal at this oint.

In the practica use of a nursing bottle constructed as set forth in theforegoing ,description and illustrated in the accompanying drawing, itis evident that the contents of the'bottle are prevented from iiowingout through the ports or apertures 7 by the engagenent of the majorcentral portion of the valve 8 with the raised portion 6 of the ca 4.When the contents of the -bottle are suc ed out through the nipple 3, itis clear that the valve 8 wlll rise from the elevated portion 6 of thecap, and air will be drawn in through the apertures 7 and the slit orincisioni) in the valve, thereby avoiding any collapsing of the nipple,and insuring that the infant shall properly obtain milk orl other liquidwithin the bottle, thus overcoming animportant cause of colic. It willalso be seen that by my invention, the cap 4 may be easily detached fromthe body portion of the pend upon the nipple to provide means forAPatented may' 1 1, 190e.

whenever necessary to adjust the parts and that when detached, the.bottle may be thoroughly cleansed.. y

Having thus described the invention, what I claim is: l

1. A nursing bottle, the body portion of which is formed with an openinga cap secured to the body portion and c osing said opening, said capbeing formed with a raised ortion, and air inlet apertures, and a valvebottle` termed with an opening therein above said raised portion anadapted to normally rest upon said raised portion of the cap, as and forthe purpose set forth.

l2. vA nursing bottle, the body portion of which is formed with an openbottom, a cap secured to said body portion and closing said bottom, saidcap being formed with a raised portion and a series of apertures aroundsaid raised portion, and a valve membrane se- 2o cured between said bodyyortior'a. and said cap and formed with a slit, t e litted portion ofthe valve being adapted to rest upon the raised portion of the cap.

In testimony whereo I aix my signature 2.5 in presence of two witnesses.
